Patent GB-2122693-A (GB)
Title: Improvements relating to pumps
Inventor: FRANCIS DAVID THEOPHILUS
IPC: F04B13/02
Filed: 1983-06-13
Abstract: A pump, primarily for showers, uses the high pressure cold water supply to drive a double acting piston (4) in a cylinder to which the hot water supply (41) is also directed, thereby boosting the hot water pressure. Mixing of hot and cold is achieved by bleeding off cold water from the supply by a valve into the outlet, reduction in delivered hot water as a result of less drive to the pump being compensated by this diverted cold water. The cold water is admitted to the cylinder via valves (30) operated through a lost motion connection (9, 12, 14, 18, 17, 22, 25, 27, 32) to the piston (4) so that each valve event occurs at the end of a stroke. The hot water is admitted to and discharged from other parts of the cylinder through non-return valves. <IMAGE>

Title: A feeler for tenter clip chains
Inventor: CRAMER HANS
IPC: D06C3/04
Filed: 1983-07-07
Abstract: Arranged with play in a slot of a feeler 4 is a knife 6 the cutting edge 7 of which is at all times adjusted parallel to the plane of a clip table 8. This parallel adjustment is possible because the longitudinal edge 10 of the knife 6 opposite the cutting edge 7 is convex and is supported on a correspondingly concave depth (upper) limit of the slot. A bolt 13 prevents the knife 6 from dropping out by extending through a perforation in the centre of the knife 6, the diameter of the perforation being greater than the diameter of the bolt 13 so that parallel adjustment of the knife 6 is not hindered. <IMAGE>
